PURPOSE:To economize the power consumption, by electrifying an exposure controlling circuit immediately before photographing, in a cinecamera which is capable of interval photographing. CONSTITUTION:An exposure controlling circuit 4 for controlling a diaphragm is electrified when a transistor TR1 is turned on. That is to say, when an EE switch SW1 is closed by depressing the first stage of a release button 1, a point I becomes an L level, therefore, an NOR gate output becomes an L level by gates AND6, AND9. In case of interval photographing, when a switch SW'2 is closed, a binary counter 10 is operated, gates AND1 and AND5 attain an H level jointly with an output of a decoder 12 at a prescribed second time interval (or after the time interval), and the transistor TR1 is turned on. Since the exposure controlling circuit is not electrified during said time, the power consumption is economized remarkably. |
